Hello
My friend told me today then even if u enable multi core from bios ur windows still uses still 1 core. I have core 2 duo processor a and i term 2 processors as @ physical processors. See the pic down and guide if i change the number of processors to 2, then only my windows will utilize two cores? Is this option for core or processors?
yes it you enable both windows wit use two and enable max ram as well your computer will go faster.
Those settings are for disabling not for enabling. Windows is already aware of your hardware and does not need to be told. So just leave it alone.
So it will go like this:
Microsoft is assuming that Multi-core is enabled from Bios
Number of processors. Limits the number of processors used on a multiprocessor system. If the check box is selected, the system boots using only the number of processors in the drop-down list.
This option is only for enabling or disabling different core through Windows interface. I hope I am totally right.
If you select Processor 2, then your both cores will be disabled. How will Windows start?
According to Microsoft support:
This switch sets the number of processors that Windows will run at startup. With this switch, you can force a multiprocessor system to use only the quantity of processors (number) that you specify. This switch can help you troubleshoot performance problems and defective CPUs.
it means if you have a Quad-Core processor, if you select 3, then 1 core will be disabled and 3will work. If you select 2, then 2 will be disabled and 2will work. It goes in ascending right :S?
Hello Saeen,
Yes, that would be correct. :)
